Pro
Contra
Incluso aunque el HP EliteBook 820 G4 sea solo una actualización Kaby Lake, podría resultar interesante para los poseedores del predecesor. Sin embargo, esto no es solo por el mayor rendimiento de Kaby Lake ante Skylake.
Una duración de batería significativamente mayor hace (aún más) atractivo este ordenador.
Independientemente de la carga de trabajo, el ordenador se mantiene en buena temperatura y funciona de forma silenciosa la mayor parte del tiempo. Esto último es cierto mientras que el ventilador no funcione o lo haga a baja velocidad. De otra forma se escucha un ligero silbido. Esto no debería ocurrir en dispositivos de este precio; más aún después de que esto fuera ya criticado en su predecesor.
El rápido NVMe-SSD asegura una buena respuesta del sistema. Es posible reemplazar el SSD. Esto requiere extraer la parte inferior del portátil - lo que no requiere mucho esfuerzo. El teclado y la carcasa no han cambiado: HP ofrece la calidad habitual.
Apenas podemos decir cosas buenas de las pantallas de los portátiles de negocios de HP. Sin embargo esta vez las cosas son distintas: HP ha incluido un panel IPS brillante, con contraste y buenos ángulos de visualización. Hasta los colores son muy decentes sin realizar ninguna calibración.
